: inex The nature of my invention understood by reference to the accompanywnmu s. sum, or rrr'rssuae, ramrs-rnv-mm sfrmmm- Toallwhmnitmayconcm:

Be it known that I, Wnlnun S. Emo'rr of Pittsburg, county of. Allegheny, State oi Pennsylvama, have invented va new and useful Improvement in Strainers, of which the following is a full, clear, and exact descrip tion, reference being had to theaccompanying drawings, forming part of this specification.

paratus, and more particularl tostrainer apparatus which is,-design to be submerged in a lake, pond, reservoir, or other body of water. I v

The object og/my invention is to provide apparatus of/t v nsive in the construction and in which the intake/or strainer partg'are; in duplicate, and are so constructed and arran I that either branch of the intake may sepa; rately used, while theother branch may be closed and the strainer elemept raised to the surface for cleaning, repairs,-etc.

ing drawings, in which'- Figure 1 is a front elevation of strainer apparatus embodyin my invention; Fi 2 is a side view of t e same partly bro en away; Fig. 3 is a vertical-section of a portion of the apparatus; and Fig. 4 is a see- I tion on the line IV-I-V of Fig. 1.

Referring to these drawings, the numeral 2 designates a supporting framework which may of any suitable construction and which is set within the body of water from which the supply of water is to be taken. This .framework is of suflicient height, so that its upper portion will project above the surface of the water.

3 designates a vertical pipe having an 01!- take connection 4, at its upper-en and a branched'intake 5'at its lower end, the lower end of the pipe 3 bein connected to the intake between its two i et ports 6 and 7,

8 and 9 designate two perforated strainer cages or baskets which may be of perforated metal, wire cloth, or of any other usual or suitable character, and which are arranged to seat upon the respective branchesof the intake over the inlet'p'orts 6 and 7. Each strainer cage or basket is provided with guide lugs or projections 9, which have a s iding engagement with vertical guide rods 10, which are secured at their lower ends to the intake connection and which extend up- I wardly and are provided with bearirgs members 2".

of the strainer 0 My invention has relation to strainerap is kind, whichis simple and.

will be best.

l at their upper ends in one .of the top ame provided near their lower ends with buttons 11, which, by rotation of the rods may be turned so as to enga e the bottom 12 k or baskets, an hus hold sa d ca es or baskets securely to their seats over t e inlet ports. For this urpose of .actua ti n'g these rods to set and reease the buttons, they ma handles .01 cranks 13,'at eir upper ends.

Thestrainer cages or baskets raised or lowered b .means of chains, cables or the like 14, whic extend from the baskets upwardly and over winding shafts 15, journaled at the u per a separate sha cage or basket. The free ends'of the chains or cables are preferably counterweightethas shown at 16. Each cage valve late 17 which, when the cage or basket 1s in position for use, is seated within and closes the up 'r'and otherwise open end of the cage or asket, to prevent the direct entrance of water thereto. Each of these valve plates is carried by a vertical rod 18, which extends upwardly through the framework and has a threaded rtion 19 near its upper end, which works m a nut 20. The vs vs plates are of proper diameter to properly c baskets and to be moved through the baskets so that when one of the baskets, is raised, the correspondin valve plate can 'be moved downwardly means of its actuating rod, to close the in at port. v

Theo ration will be readily understood. Normal y but one of the cages will be in use, as shown in Fig. other basket being raised to the top of the frame or support- 21 and the corres onding valve being moved down to close t e inlet port at that side. Whenever the basket or cage which is in use becomes clogged or requires cleaning, the other ca or basket is lowered by t e operation'o the winding shaft, its valve plate is raised in a position to close the upper end of the ca e or basket, the ,othervalve plate is lower to close its inlet ort, and the cage or basket'to be cleans is raised to the surface. In this manner, one of the strainer ca es or baskets may always be in condition an position for use. If it is desired, both cages or baskets Theserods are also preferably" be P id with rtion of the frame 2, t15 ng provided. for each o bask is p ovided wit a os'e the upper ends of the cages or or baskets 1, the

can be used at the same time and may be alternately raised for'cleaning. It will be obvious that various changes can be made in the details of construction and arrangement of the parts. Thus, any suitable means may be employed for raising and lowering the baskets and for guiding them in their movements, the valves may be: actuated in any other suitable manner, and

other chan es may be made without departing from t e spirit and scope of the invention, as defined in the appended claims; I claim: v

1. In strainer a paratus of the character described, a branched intake, and a strainer element arranged to seat over the inlet port of each branch of the intake, means for separately raising and lowering the strainer elements, and a valve member for each strainer element which in one position closes and a strainer.

end of the strainer element, said valve member being movable through the strainer element, and means for actuating said member, substantially as described.

'3. In strainer apparatus of the strainer elements mounted upon the up per portion of the support, guides for the strainer elements, and valve means arranged to alternately close "each inlet port'and the upper end of the correspondin strainer element, substantially as describe 4. In strainer apparatus of the character described, an intake having an inlet' port, a valve seat around said port, a strainer ele ment arranged to seat. around and over the port, means for raising and lowering said element, and a valve I member adapted to close the top of the strainer element in one position and to close the inlet port in another position, substantiallyas described.
